Using thread/state rules, we can do (but expect to do more than) the following things: we can construct the explicit expressions for the SS states corresponding to a set of bulk extremal surfaces in the SS duality, and nicely characterizing their entanglement structure; use the locking bit thread configurations to construct a new toy model of the holographic principle and actually, we explicitly give the relationship between this model and the holographic tensor network models; naturally understand the so-called kinematic space [1]}, [2]}, endow it with the interpretation of microscopic states such that to explain that the entropy is proportional to volume therein; in some sense quantitatively characterize the famous “It from qubit” thought experiment [3]}, that is, by removing the entanglement in the boundary quantum system, the bulk spacetime will accordingly deform, or even break up.
